DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Researchers use DNA barcoding to test food products claiming to have ‘wild mushrooms’

Harvesting wild mushrooms requires an expert eye to distinguish between the delicious and the inedible. Misidentification can have a range of consequences, from a disgusting taste and mild illness to organ failure and even death.

Research could enable clinicians to produce patient-matched cells for treating muscle-related diseases

Investigators who previously developed a recipe for turning skin cells into primitive muscle-like cells that can be maintained indefinitely in the lab without losing the potential to become mature muscle have now uncovered how this recipe works and what molecular changes it triggers within cells.

Scientists propose innovative method to test the effectiveness of coronavirus medicines

South Ural State University scientists have proposed an innovative method for testing the effectiveness of medicines for coronavirus. According to the researchers, it is necessary to focus on the maximum coincidence of the ligand and the receptor. The results of the work have been published in the highly-rated journal "Molecules"(Q1).
